The cover picture shows Pt‐catalyzed reductive cyclizations under environmentally benign hydrogenation conditions. In a reaction vessel equipped with a hydrogen balloon, the Pt complex catalyzed the cyclizations of yne‐enones, yne‐aldehydes, and yne‐dienes to form five‐ and six‐membered rings. The reaction scope and deuterium labeling studies show the expanded reactivity of the Pt complex for the hydrogenative cyclization of various π systems. Details are discussed in the Short Communication by H.‐Y. Jang et al. on page 6091 ff. The authors acknowledge Won‐Seob Cho for the cover page design.
